"Moreover, the female form, and the cavity of the womb, most suitable for receiving, and cherishing, and vivifying the germ, who does not believe that it has been made as it is by reason and foresight?—because in that part alone of her body the female differs from the male, in which the fœtus being placed, is kept and cherished. And again the male differs from the female only in that part of his body in which is the power of injecting seed and propagating mankind. And in this there is a great proof of providence, from the necessary difference of members; but more in this, where, under a likeness of form, there is found to be diversity of use and variety of office. For males and females equally have teats, but only those of the female are filled with milk; that, as soon as they have brought forth, the infant may find nourishment suited to him. But if we see the members in man arranged with such method, that in all the rest there is seen to be similarity of form, and a difference only in those in which their use requires a difference, and we neither see anything superfluous nor anything wanting in man, nor in woman anything deficient or in excess, who will not, from all these things, acknowledge the operation of reason, and the wisdom of the Creator?
